G313331329 22.4 mm Dia. UVFS Double-Concave Lens; EFL=-30mm 1064nm
This is a G313331329 double-concave lens, featuring a diameter of 22.4 mm and a center thickness of 1.5 mm. The lens is designed with a high-quality UVFS material, specifically the UVMAL-1965 variant, which is sourced from Qioptiq Photonics. The lens is specifically designed for use with a wavelength of 355 nm.
The lens has an effective focal length (EFL) of -30 mm, indicating its concave nature. The first radius of curvature (R1) is -30.287 mm, while the second radius of curvature (R2) is 30.287 mm. These specifications suggest a symmetric concave lens, which is further confirmed by the inner and outer radii being both 0 mm.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating enhances the lens's performance in specific applications, particularly those involving YAG lasers. The lens's shape is spherical, which is a common choice for its wide range of applications and ease of manufacturing.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. More information, including pricing and availability, can be found at the provided weblink.
